Oh, I feel scolded :P
The truth is, you should be grateful to me because I'm pointing out the weakness of your DV system in stopping spam based on a vulnerability related to user tagging.
If I were a truly annoying guy, I could create accounts like that and keep repeating this behavior, spamming whatever I want, and DV wouldn't have any influence. You're lucky it was a one-time action because I'm a guy who simply likes experimenting with different approaches and finding loopholes.
Your constant repetition of the mantra that DV is for this very purpose is like a maniac stubbornly repeating that the thief broke in bypassing your alarm, which causes countless other false positives and problems on a daily basis. It doesn't mean the alarm is useless, you just keep claiming that this system is necessary. XD
Downvotes are the reason why this ecosystem, which I also once supported and promoted, will collapse sooner or later. Remember my words ;)
Of course, if you understand that this was the main reason and why, and you don't buy some other fairy tales they sell you.
fdw:
